Games

Autosokoban

I created an algorithm to automatically generate sokoban problems of increasing difficulty. Check it out! The first levels are trivial, but somewhere around level 10, perhaps 15, you will find that the puzzles are becoming quite challenging.

Level:  0

Moves:  0

(Use keyboard or click above.)

These levels were generated using random seed 372551990.

Use the following URL to get back to this particular puzzle:

I would like to thank Murase-san, Matsubara-san and Hiraga-san who approached this subject in an academic paper called Automatic Making of Sokoban Problems. In general, my algorithm is fundamentally different than theirs, but the first step (generating rooms) is performed as described in the paper.

By the way, I should warn you that this game is highly addictive. Arm yourself with plenty of coffee and chip music.

I was looking at level 100 and above, and they were pretty mean. I hope I didn't suffocate your web server with generating them!

How fast is the solving algorithm, and how does it compare to that in the original paper which inspired you, and how quickly can it (your own algorithm) solve f.ex the typical level 100's on a given system?

No problem. =)

The solution is a bi-product of the puzzle generation algorithm, so it would take no additional time.

hey!

very nice job! i love this game. levels are getting more and more tricky, but you never know if the next one is easy or not. :) is there any way to install the programm on a cell phone? how complex is the algorithm to generate the levels?

Thanks! The algorithm needs a lot of RAM, so it's probably not feasible for a midlet. Some day, when I get the time, I'll publish the source code and a description of the algorithm.

Oh, super! I am very much interested in the source code. To avoid the RAM-problem, one could split the programm into a "level-creator", that calculates for example level 1 to 100 of a seed und saves it in a small file, which could be read by the second program running on the cell-phone.

I've done it in about a minute. It's not impossible. Start by pushing higher the one that's above you at the start position, and then one point higher the one below you.

I'm interested in the generation algorithm too. :)

Would it be ok if I took two or three levels generated by this program and uploaded them to a certain freeware game similar to Chip's Challenge? You and your wonderful sokoban generator would recieve the credit for creating the levels, and additionally I would provide a link to the generator here so others could enjoy it.

It's some sort of overflow I'd say as 2147483647 = 0b01111111111111111111111111111111 (so one zero and 31 one's)

Hi! I saw your mail about this; sorry for not replying sooner. Yes, you can use levels that you got from my level generator. But don't hook up the app directly to the online generator, because that would increase my bandwidth requirements. Include a credit and a link to my page somewhere.

Cool stubled on this just now!

My first "app" was a J2ME-midlet originally made for the SE T610. It was Sokoban, with the feature of "in-app-purchase" ;) Beeing able to download new level-sets from my webserver that kept the levels as strings in MySQL. The midlet sent max size of it's screen to the server and only got levels that fit. It worked very well on most j2me enabled phones i tried it on, even the low end ones. It can still be downloaded:

http://adent.dyndns.org/wap/apps/Sokoban/index.wml

But the level download feature does not work right now, shall try to fix it server side some time.

When everything kind-of-like worked the project was'nt fun any more... And also, lack of freely available levels...

It would be cool to finish it up some time.

The level is actually not as difficult as you think.
Using the upper path as a one-way sliding door makes it easy.

To make it more interesting, you can actually eliminate the upper path as a one-way sliding door by adding a wall.
Like this:

#####-----
##--###---
#@--$-####
##-##----#
-#.*.-.$-#
-##$-$-$.#
--#-.$.-##

Still relatively easy.

I spent a little time on Autosokoban this summer vacation. I worked hard and the end result was, of course, a failure. Now I have to say that I really looked down on this problem at the beginning. I think many ordinary people may not realize the complexity of this matter as much as I did at the beginning.
Now I see your website and find that you have solved this problem perfectly more than ten years ago. Thank you, this is an impressive work.

hey!

very nice job! i love this game. levels are getting more and more tricky, but you never know if the next one is easy or not. :) is there any way to install the programm on a cell phone? how complex is the algorithm to generate the levels?

Thanks! The algorithm needs a lot of RAM, so it's probably not feasible for a midlet. Some day, when I get the time, I'll publish the source code and a description of the algorithm.

First of all, thanks for this great sokoban generator. Generates small but difficult puzzles progressively. Were you able to publish the source? Even though I am not a programmer myself, this will be a great gift to the sokoban community.

Cool stubled on this just now!

My first "app" was a J2ME-midlet originally made for the SE T610. It was Sokoban, with the feature of "in-app-purchase" ;) Beeing able to download new level-sets from my webserver that kept the levels as strings in MySQL. The midlet sent max size of it's screen to the server and only got levels that fit. It worked very well on most j2me enabled phones i tried it on, even the low end ones. It can still be downloaded:

But the level download feature does not work right now, shall try to fix it server side some time.

When everything kind-of-like worked the project was'nt fun any more... And also, lack of freely available levels...

It would be cool to finish it up some time.

Wait wait aren't you the developer from sokoban Garden ?
Levels were really well thought.

Hey Linus, can you provide a link to the source code or offline binary so that I can play offline ?

This one *actually* has to be impossible. All the moves are forced and create a deadlock afaik?

I was looking at level 100 and above, and they were pretty mean. I hope I didn't suffocate your web server with generating them!

How fast is the solving algorithm, and how does it compare to that in the original paper which inspired you, and how quickly can it (your own algorithm) solve f.ex the typical level 100's on a given system?

No problem. =)

The solution is a bi-product of the puzzle generation algorithm, so it would take no additional time.

http://www.linusakesson.net/games/autosokoban/?v=1&seed=1371159436&level=100, this puzzle seems to be unsolvable, because the boxes on the left-top, left-middle and left-bottom competes for the target squares in the left-bottom. Is there any bugs? If not, hope you can provide a solution, thx :)

I was able to solve it just now. But it was a nice, tricky one. Good find!

I liked this one. Funnily enough, the next level of the same seed was way trickier for me to solve.
